JAXA Bounce Laser Beam Between Moon’s Surface and Lunar Orbit

NASA’s  has twice transmitted a laser pulse to a cookie

This was an important accomplishment for NASA because the device is not in an optimal position.

To boost the chances of reaching their target, the LRO team worked with JAXA to determine the exact location and orientation of SLIM

NASA engineers predicted when LRO’s orbit trajectory would bring it to coordinates

LRO’s altimeter wasn’t built for this type of application

So the chances of pinpointing a tiny retroreflector on the Moon’s surface are already low

The first time a laser beam was transmitted from LRO to a NASA retroreflector and back was on Dec

NASA’s retroreflector has eight quartz corner-cube prisms set into a dome-shaped aluminum frame that is 2 inches wide

The retroreflectors could guide Artemis astronauts to the surface in the dark
